Commentaries of the Four Authorized Vaisnava Sampradayas

Of sound vibrations Lord Krishna's vibhuti or divine, transcendental
opulence manifests as the sacred monosyllable OM which is uttered before
every Vedic ritual can begin. The words ekam aksaram directly refers to OM.
Of all acts of worship and propitiation Lord Krishna's vibhuti manifests as
japa-yajno or the reverential chanting of the holy names of the Supreme
Lord with bhakti or exclusive loving devotion. Of immovable things His
vibhuti is the towering Himalaya's, the highest mountains on Earth.

Ramanuja

Ramanuja's Commentary

Lord Krishna reveals that of the holy sages His vibhuti is Bhrigu. The word
giram means articulate sound vibrations of these Lord Krishna's vibhuti is
the all powerful monosyllable OM. Of all yagna or propitiation and worship
to the Supreme Lord, the best and most elevated is japa-yagno the
reverential and devotional chanting of the Supreme Lord Krishna holy names.
Of terrestrial mountains His vibhuti is the mighty Himalayas.

Kumara Vaisnava Sampradaya:

Nimbaditya

Kesava Kasmiri's Commentary

Of articulate sound vibrations Lord Krishna's vibhuti or divine,
transcendental opulence is the monosyllable OM the root of all sound. Among
yagna or propitiation and worship of the Supreme Lord, His vibhuti is japa-yagno or the devoted chanting of the Supreme Lord Krishna's holy names. Of
immovable mountains His vibhuti is the Himalaya mountains.
